Sampled Fiber Bragg Grating spectral synthesis.
In this paper, a technique to estimate the deformation profile of a Sampled Fiber Bragg Grating (SFBG) is proposed and experimentally verified. From the SFBG intensity reflection spectrum, any arbitrary longitudinal axis deformation profile applied to a SFBG is estimated. The synthesis algorithm combines a custom defined error metric to compare the measured and the synthetic spectra and the Par...
متن کاملMulti-parameter Sensing System Using Sampled Fiber Bragg Grating
We propose a Gaussian sampled fiber Bragg grating for multi-parameter sensing system. The sampled fiber Bragg grating combines the characteristics of fiber Bragg grating and long period grating. The transfer matrix method has been used to obtain the transmission spectrum of the grating. The shifts in narrowband loss peak and broadband loss peak in the transmission spectrum have been utilized to...
متن کاملFiber Optic Bragg-Grating Sensors
In-fibre Bragg gratings are sensor elements which are photo-written into optical fibre using intense ultra-violet laser beams and have the potential for the measurement of strain/deformation and temperature with applications reported including monitoring of highways, bridges, aerospace components and in chemical and biological sensors. The development of a fiber Bragg grating (FBG) measuring sy...

متن کاملEfficient numerical method of the fiber Bragg grating synthesis
A new numerical method is developed for solution of the Gel’fand – Levitan – Marchenko inverse scattering integral equations. The method is based on the fast inversion procedure of a Toeplitz Hermitian matrix and special bordering technique. The method is highly competitive with the known discrete layer peeling method in speed and exceeds it noticeably in accuracy at high reflectance.
